I stopped Laura, pulling her head off of my cock.
"You are very good, Laura. I bet boys go wild over what you do with your tongue." She smiled shyly and my heart melted a little, "But it feels like you are doing what you think you are supposed to do. That's how guys describe what they want because that is how porn displays it. Real sex is not about that moment of ferocity. It is about building up to it. I want you to do it again, but this time, go slow. Do what you feel like. If you want to hold it for a minute, just hold it. If you want to lick a little, lick a little. If you want to choke on me, by all means, do it, but I want to feel how bad you want me in your mouth."
She hesitated, then brought her lips to the tip of my cock, kissing its swollen head. She started sucking me, lightly and slowly, and I groaned in pleasure. Now, this was fantastic. Sarah scooted over to me and offered me her lips. I kissed my niece gently, in time to her friend's sucking. What a treat she had brought me. I wrapped my arms around her, sliding my hand down her back to her thighs, then up under her skirt. I stroked the outside of her panties, feeling how hot and wet she was. I knew she must be going crazy, seeing my cock in her friend's mouth. I found the side of her labia and stroked it up and down, avoiding her clit. Then I pulled away and whispered, "I want you to go do the same thing to your friend."
Sarah smiled up at me and then slid off the couch to join Laura on the floor. Laura's ass was already up in the air, giving Sarah adequate access to her pussy. She shyly put her hand between her friend's thighs and began stroking her with the same slow, steady rhythm that I had used. I felt Laura pick up the rhythm in her sucking, and her intensity increased as her pleasure began to mount. They were such a sight to see, all young, perfect flesh kneeling before me, begging for my attention.
"Sarah," I said quietly, "I want you to pull Laura's panties to one side, and give her a little lick with just the tip of your tongue." Sarah did as she was told, and I felt Laura's throat vibrate as she moaned. I was finally really getting into this. I pulled Laura's head back again, and bent down to kiss her fully on the mouth, letting my tongue linger and explore her cavity for a moment. When I broke the kiss all three of us had silly grins on our faces.
"Why don't we go to my room?" I suggested.
In my room we all three got naked and the two girls lay on my bed. I knelt between them, one hand on each of their outside hips. They looked at each other and giggled.
"So, you learned how to take things slow with a man, but I doubt that you have ever had a man go slow with you, or you would have already known how to do that. So why don't you sit back and relax and I will have Sarah show you how to build an amazing orgasm."
Laura curled up on her side and Sarah lay flat on her back, spreading her thighs, eager for what I was about to do. I reached up with one hand and began gently kneading her breast, while I spread her pussy lips with my other hand and dipped my tongue down to her hot juices. Two years later and I could still go down on her for hours. There was absolutely no rush. I savored her flavors and the gentle moans that escaped her writhing body. I was slow and steady and she began to build in intensity. Taking my cue from her I lapped harder, pulling at her skin with my teeth and pressing my tongue underneath the nub of her clit. I could feel Laura staring at us in awe. I saw her own hand wander down between her thighs and I felt a pang of pity for her, wanting to allow her to join.
Just when Sarah was about to climax Laura could stand the distance no more and reached out her hand to replace mine on Sarah's nipples, tugging with the same amount of intensity as she leaned in to kiss my niece's soft mouth. The new stimulation surprised Sarah and so she did not climax as hard as she had been about to, but she did not seem to mind as her hands eagerly roamed over Laura's torso. My own hand freed from its earlier task I reached over to Laura's dripping pussy and began to stroke it with the same rhythm as Sarah's. The two girls moaned sweetly into each other's mouths. I went back and forth with my mouth. Sarah was sweeter, and Laura was more pungent but they both tasted of happiness and youth. Eventually I sat up, keeping one hand working each of them as I watched them kiss and suck at each other's nipples and mouths. They were a beautiful pair.
I stopped stroking the girls just long enough to find one hand of each of theirs and guide it to the other's pussy. They were shy at first, timidly stroking the outside. But I knew that they both ached to be filled after my working of them and so I guided their fingers deep into each other. As soon as they felt the wetness around their fingers they both grew excited and began to more vigorously pump in and out of the other girl, never stopping their intimate kissing and adorable moaning. As they progressed I guided another finger into each girl, and then another, until they had all four fingers working into the sopping wet pussy of the other. I could hear the magical squishing sounds and their groans all around me. Finally I could sit back and just watch.
As I moved away from them they got closer, spreading their legs open further for the other. Sarah was less shy than Laura and was now down to all four knuckles of her hand, twisting her palm in little ways that made Laura start to scream with pleasure. It took Laura a while longer, but soon she was returning the favor to Sarah.
I stood over the bed and reached down to stroke myself as I watched the two girls play. I was not sure if they would go all night or have to stop the intensity of their session soon, but I knew I wanted to burn the image of their tangled bodies into my mind. They had long ago abandoned the gentle moans and were grunting and screaming with pleasure.
"Yes, baby, yes," Laura cried out, "Mmm, fuck me Sarah, harder, please harder!"
And Sarah fucked her harder. She bit Laura's lip and shoved her entire fist into the other girl's dripping cunt. "Yeah, you want that you fucking slut?" she cried, unaware of what her mouth was saying, "You want me to give it to you like that? Well, you better give it to me to. Fuck me, you cunt. I want to feel you deep in me."
I could not believe both girls were fisting eachother. True, their hands were smaller than mine, but I had been so afraid the first time I fisted a girl. Here they were, enjoying the spreading of their cunts without hesitation, putting on the most beautiful show for me. I had not even realized how hard I had started to stroke my cock, but I looked down and my own hand was working with speed and pressure that was bringing me near orgasm. That was okay though, because I knew with their intensity that neither of them could be far off.
Suddenly Laura's body seized, and she bucked hard against Sarah's soft naked frame.
"Fuck, Sarah! I am, I am, I am," she shuddered. Her orgasm tripped Sarah off and she kissed her friend hard and rolled her eyes back into her head. I could not hold back my own orgasm any longer and shot my load in hot streams over their arched bodies.
"Fuck!" I cried, collapsing in bed between the two of them. The three of us had a collective sigh, and then Laura laughed with happy freedom. And I thought, Damn, this will be a good weekend after all.
